That can happen randomly. There's no logical reasoning to it. For example I got that around 5 times and I had a SKILL which was at 40...and it said -32.... it could have done -32 or +32, but it didn't show any option...

So what do we do?

Set anything to 0. More than 1 skill if it doesn't work.

player.setav "skillhere" number

So..do this. Set 2 skills to 0 by going -100 for number.

Right after u do that WHILE your screen still says -32 (in the background)

just hit "player.setlevel 16" or any number before you level--as long as you aren't at the LEVEL 20 screen ok?

Then hit advlevel

and exit console. You will see new screen with + skill points to add and Zero's for the skills u removed points from
